Can Oracle Instant Client be used with Toad to establish an LDAP connection?
Unfortunately Toad for Oracle does not work with the Instant Client because the required Oracle DLL (OraLDAPClnt.dll) is not included in the Instant Client.
LDAP connection can established with full client. For LDAP to function correctly, both SQLNet.ora and LDAP.ora files must be placed in the TNS_ADMIN folder.
When operating in no-client mode, Toad uses its internal code to communicate with LDAP, retrieve the list of TNS entries, and then establish a direct connection.
